Although stressors are frequently linked to several negative health outcomes, experiencing stressors may be necessary for enhancing performance. At present, the literature is lacking a unified, comprehensive framework that accounts for both positive and negative outcomes following stressors. Therefore, we introduce the framework of hormesis, which has been applied in biological research for decades. According to hormesis, small-to-medium doses of a stressor can stimulate an organism's response, while large doses cause detrimental effects. In this article, we argue that these dose-response dynamics can be found in various domains of performance psychology (i.e., eustress and distress, psychological momentum, emotions, motivation, confidence, cognitive performance, training, skill acquisition, adversity, and trauma). Furthermore, hormesis also accounts for the inter- and intra-individual variability commonly found in responses to stressors. Finally, from an applied perspective, leveraging hormesis may stimulate new psychological interventions that mimic the well-known effects of (toxic) vaccinations at the level of behavior.

However, this relationship turned out to be more complicated. The current paper describes, by using personal lighting conditions in a field study, further exploration of the relationship between light and subjective alertness during daytime. Findings show that this relationship is highly dependent on the individual. Although nearly all dose-response curves between personal lighting conditions and subjective alertness determined in this study turned out to be not significant, the results may be of high importance in the exploration of the exact relationship.

Samenvatting: In het kader van een afstudeerproject zijn data van 33 kinderen verzameld die een X-abdomen onderzoek ondergingen in het Wilhelmina Kinderziekenhuis. Uit deze data zijn curves afgeleid van Dosis Oppervlakte Product (DOP) ten opzichte van het lichaamsgewicht om te dienen als Diagnostisch ReferentieNiveau (DRN). De spreiding in de data leidt echter tot onzekerheid over de beste DRN-curve. Die curve is bovendien slechts gebaseerd op de data van één ziekenhuis en is daarmee hooguit bruikbaar als lokaal DRN. Door deze studie te herhalen in andere ziekenhuizen en meer data te verzamelen zou een nationale DRN-curve afgeleid kunnen worden. Zo’n curve zou de toetsing van doses aan DRN’s voor kinderen vergemakkelijken.
